12-ALT 4 Concept Exhibit DRAFT.pdf

This is a concept exhibit for the Town N' Country Regional Drainage Improvements Project, a stormwater engineering design initiative led by the Hillsborough County Engineering & Operations Department in Florida. The exhibit presents Alternative 4 design conceptual plans for Sweetwater Park, which is a key component of the regional drainage improvement effort. The design includes approximately 2.5 acres of stormwater pond with inflow and outflow culvert connections at locations and sizes to be determined. The plan shows existing site features including Chelsea Street, Bray Road, Burkett Circle, existing nature trails, and an existing pond. The digital elevation model ranges from 0.3 to 11.3 feet (NAVD88), with top of bank at approximately 7 feet and toe of embankment at approximately 0 feet, utilizing a 4:1 side slope. The exhibit is dated February 28, 2024, and represents a draft status for ongoing project development.

The associated contract opportunity requests comprehensive stormwater engineering design services estimated at $1,350,000.00 and includes design, plans preparation, specifications and contract development, environmental permitting, subsurface utility engineering surveys, topographic mapping, specific purpose surveys, right-of-way acquisition services, title search reports, utility coordination, geotechnical investigation and analysis, post-design construction services, construction phasing and maintenance-of-traffic analysis, and landscape architecture and design services. The project is managed by Hillsborough County Engineering & Operations Department and seeks experienced and qualified professionals to deliver these comprehensive engineering and design services.
